Ignore my numerical vote--this is a bad movie but only in the best possible way!! I am a bad movie fan, but not all bad films. Some bad films are dreadfully boring and I hate them (such as "The Conqueror" or "Cracking Up"). However, a small group of film are bad but hilariously bad--so bad, so silly, so unbelievably stupid that you can't help but like them. I love films like "The Apple" and "Rock 'n' Roll Nightmare" because they don't take themselves seriously--and they revel in their badness! Now this isn't to say the film is all bad--the music, for 80s hair band tunes, is great stuff and made a wonderful soundtrack to an apocalyptically bad film.
This film is basically like taking "Halloween" or "Friday the 13th" and injecting them with great tunes--along with taking about about 98% of their budget! It's hard to imagine, but the film was made in only seven days and cost a paltry $53,000 to produce. This budget, adjusted to inflation, makes it even cheaper to make than Ed Wood's "Plan 9 From Outer Space"! The film begins with the slaughter of some family. Then, many years later, a rock band goes on a retreat in the middle of no where (Canada) to work on their music and cut their next album. However, the place is infested with demonic hand puppets who wipe out the cast one by one until their is a final climactic battle between a large-breasted guy and a giant Satan puppet that throws evil starfish at him! You really have to see it to believe how bad it is--but also how incredibly funny it is.
By all means watch the film--it's horrible and funny. But be prepared--like so many slasher films of the day, there is LOTS of nudity. But, considering that the movie is all about Satan and his hand puppets butchering rock stars, you wouldn't think to show this to kids or your mother! So amazingly bad AND cool at the same time, you just have to see it. And, if you can't stand the film (because it is dumb), just listen to the songs--they really are awfully good.
